The "anaphalaxis" I was talking about was the alternative to the sub crush, and what happened to the billionaire that is the subject of the article, so I think you might have misunderstood me?

Nope. The titan sub was having trouble. They dropped weights and were attempting to make an emergency ascent, but it wasn't rising fast. Meaning, the density of the sub was increasing. Some people are saying leak, others say water egress between CF layers and the hull failing, meaning contraction in the middle, like squishing a tube (see the simulations for how the static deformation would look like).

Sure, the complete failure was over in milliseconds, but not the experience of being an experimental test passenger on a rich moron's death trap!

They were comparing anaphylaxis to death in the sub, not saying it was from a leak on the sub.
